摘要: Abstract 3D micro welding (3DMW) is a new freeform fabrication method which combines tungsten inert gas (TIG) welding, rapid prototyping (RP), and self-propagating high temperature synthesis (SHS). The optimization of forming parameters such as arc peak current, bead diameter contact angle was investigated. As the current increased, height titanium were decreased, but width increased. pins with needle-like dendritic microstructure α-phase formed by continuous stacking beads. Simple intermetallic alloy pin objects Ni–Al, Ti–Ni Ti–Fe systems also alternate their component wires. No pore crack observed uniform composition observed. exothermic SHS reactions should take place assist formation. ring double helix shapes directly from computer models without using molds or dies.
